然而，尽管第一次用于研究小肠疾病，胃肠道蠕动为推动它们向远端的这些吞咽设备也像休息。这在由H. Ishiguro等的纸示出。在一项研究中使用的食管囊屏幕食管静脉曲张和讨论结肠胶囊内镜检查时由G.潘和L.王未来发展检讨提及。
虽然避免了与传统的内窥镜程序和许多放射性检查所需的辐射暴露相关的镇静和插管的风险，胶囊内镜也不是完全没有风险。Retention of the capsule behind a stricture is the main concern, particularly if this is a benign disease such as Crohn’s or a nonsteroidal anti-inflammatory drug enteropathy which would not necessarily require operative intervention, and the size of this problem is assessed in the large series presented by L. M. Höög et al. These authors also consider the issue of incomplete examinations. This is less widely discussed, but is much more common than capsule retention, may necessitate repeat or alternative investigations, and is an important consideration. The potential for interference with cardiac pacemakers and other devices remains of sufficient concern for manufacturers to consider capsule endoscopy to be contraindicated in the presence of such devices: D. Bandorski et al. provide some reassurance in regard to this matter in their international survey of practice.
G.潘和L.王提供了一个迷人的洞察未来的技术进步可能使我们能够实现与这些远程设备，目前只是提供了一个成像设备，但可能发展到让运动的控制，组织或体液和治疗的采样。我们不应该失去的轨道，但是，适当地使用胶囊内镜检查的重要性，安全，有效，和R. Sidhu等。提醒我们的需要进行相应的培训和认证使用其已广泛应用于常规的临床实践设备提供服务的卓越。
